Do you know what frequencies are commonly used for cell phone signals? Today for everyone to increase knowledge .
Since the development of China’s communications industry, has gradually formed the coexistence of 2G/3G/4G/5G situation, mobile phone communication signal transmission is transmitted through a certain frequency, and the three major operators have different frequencies and network standards, which will result in the same mobile phone between the three major operators may not be common situation, then the three operators commonly used frequency what? What does frequency-based identification mean?
The frequencies of mobile phone signals of China’s three major operators are generally as follows (Lintratek 4G Mobile Repeater can be customized according to the frequency bands of other countries and regions) :
1, China Mobile: 885-909 (uplink), 930-954Mhz (downlink);
2, China Unicom: 909-915 (uplink), 954-960Mhz (downlink);
3, China Telecom: 825-835 (uplink), 870-880Mhz (downlink).
The significance of mobile phone signal based on frequency:
Signal Identification G：
The full name of G is GPRS, which belongs to 2.5G network and is a network standard for GSM mobile phone users. From the beginning of GRPS, mobile phones can officially surf the Internet;
Signal identification E
The full name of E is EDGE, short for GSM evolution technology, which is a transition technology from GSM to 3G. The speed is a little faster than GPRS, which belongs to 2.75G network. E is the mainstream mobile wireless network transmission mode in the years when smart phones have just come out.
Signal identification 3G
3G indicates a common 3G network, which has a higher data transmission rate than E. In the 3G era, with higher bandwidth and stable transmission, mobile Internet applications began from that time;
Signal identification H
H+ is the enhanced version of HSDPA HSPA+, belongs to 3.75G network, can achieve a maximum 42Mbps downlink speed, the network speed has also been further improved;
Signal identification 4G
4G is the network that most people are currently using, and it is also short for fourth generation mobile communication technology. In the transmission of audio, video and images, the speed has made a qualitative leap, and the theoretical transmission rate can reach up to 100Mbps;
Signal identification HD
HD is the symbol of high-definition calls, that is, VoLTE, referred to as high-definition voice, which is also a 4G network. The biggest role of VolTE is that voice calls are no longer carried by 2G /3G networks, and 4G networks are used to transmit voice data, support higher language coding technology, call quality is significantly improved, and support Internet access while talking.
